lisa is 6 years older than her brother Tom. Their father's age is twice the sum of their ages. How old is Lisa if her father is 32?

Respuesta :

32 = 2(x + 6)
32/2 = 16
16 = x + 6
16 - 6 = 10

10 = x , Lisa is 10.

L = T+6
F = 2(L+T)
F = 32

2(L+T) = 32
2(L+L-6) = 32
2L-6=16
L=11



Lisa is 11 years old
